EMS-GRIVORY Metal Replacement at the Highest Level

Grivory GVX opens up a completely new chapter in the field of metal replacement.

With the high-performance polymer Grivory GV, EMS-GRIVORY has been market leader in the field of metal replacement for many years now. The new material Grivory GVX now takes us a step further. With clearly improved mechanical properties, the range of metal replacement applications has been significantly widened. The exceptional performance provided by Grivory GVX is convincing in every detail!

Grivory GVX is characterised in particular by:

  • highest stiffness and strength values
  • very low warpage
  • simple processing

With its exceptional property specification profile, Grivory GVX opens up a completely new chapter in the field of metal replacement.

If all property values of Grivory GV-5H are compared with those of the new material Grivory GVX 5H, the consistent increase in performance is clearly apparent. The further development of Grivory GVX is particularly visible in its low warpage values, more isotropic material properties and flowability.

EMS-GRIVORY − The New Generation: Enhanced Performance at High Temperatures

Grivory® is the trade name for a group of technical thermoplastics manufactured and distributed by 
EMS-GRIVORY. The materials in this group are based on semi-crystalline polyamides with some partially aromatic content.

Grivory HT is a semi-crystalline thermoplastic construction material based on polyphthalamide (PPA) and is characterised by its high-performance properties.

Technical injection-moulded parts made from Grivory HTretain their shape even at high operating temperatures. Thanks to its properties, Grivory HT is undoubtedly a high-performance plastic. In terms of characteristics such as stiffness and strength, among the most important in metal replacement, Grivory HT outperforms materials such as PPS or PEEK at operating temperatures up to 120°C.

Now learn about the 'New Generation' of Grivory HT –High Heat & Hydrolysis resistance developed for the most demanding applications for Automotive and I&C.

EMS-GRIVORY − cost and weight savings at high temperatures

Use of plastics for replacement of metal has become popular with many engineers and designers due to the reduction in cost and weight that can be achieved. Leading polymer specialist EMS-GRIVORY now offers Grivory HT «High Temperature» materials which can be used in metal-replacement applications at working temperatures well above those of standard PPA.

Compared to standard PPA, Grivory HT «High Temperature» provides greatly improved performance at high temperatures with a 50 °C higher HDT/C, 50% higher E-Modulus at 140 °C and outstanding creep values. The melt temperature is also lower – a further processing advantage.

Grivory HT »High Temperature« makes it possible to design components with very low wall thicknesses while achieving shorter cycle times and overall cost and weight savings compared to standard PPA materials.

Metal replacement and lightweighting


Structural components can be exposed to severe conditions and, as a result, are often made of die-cast metals. Despite this, intelligent lightweight design solutions can also be achieved for these applications using high-quality performance polyamides from EMS-GRIVORY.

Key take away points:
  • Knowledge on injection moulding grades ideally suited for metal replacement
  • How to redesign from metal to plastic
  • A one process solution giving a cost down product
